The Hungarian government says it is submitting an anti-migration bill to parliament dubbed "Stop Soros," targeting civic groups which organize, support or finance migration.

The measures propose that such groups would need permission from the interior minister for their activities.

Prime Minister Viktor Orban, who is radically opposed to migration, claims the groups are carrying out what Orban calls a plan by Hungarian-American billionaire and philanthropist George Soros to bring millions of migrants from Africa and the Middle East to Europe.

Bence Tuzson, state secretary for government communications, said Tuesday that compared to an earlier version, the draft bill has been made even more strict based on over 600 suggestions from citizens.

Critics fear the law will be used to stigmatize or intimidate civic groups, especially those receiving funding from abroad.
